Description

A gas swirl plate homogenizer for a waste gas regenerative incinerator

technical field

The utility model relates to an air flow homogenizer, in particular to a gas swirling plate homogenizer of a waste gas regenerative incinerator.

Background technique

At present, there is generally no swirl plate homogenizer in the regenerative incinerator, and the exhaust gas with a certain pressure directly enters the bottom of the regenerative incinerator, so there is a phenomenon of uneven airflow, and uneven exhaust gas flow Into the honeycomb ceramic regenerator, the heat absorbed in the honeycomb ceramic regenerator cannot be fully exchanged, thereby wasting a large amount of fuel. At the same time, the exhaust gas contains a large amount of smoke and particulate impurities, which directly enter the honeycomb ceramic regenerator. , it is easy to cause the honeycomb channel of the honeycomb ceramic regenerator to be blocked, which affects the efficiency and service life of heat exchange.

Utility model content

The technical problem to be solved by the utility model is to provide a gas swirl plate homogenizer for a waste gas regenerative incinerator, which can filter the waste gas, reduce the smoke and particulate impurities in the waste gas, and at the same time make the air flow evenly distributed, which can improve the honeycomb ceramics. Heat exchange efficiency and service life of the regenerator.

The technical scheme of the utility model is as follows: a gas swirl plate homogenizer for a waste gas regenerative incinerator, comprising an inner cylinder and an outer cylinder which are arranged on the inner and outer sides of a coaxial core, and the inner cylinder and the outer cylinder are evenly distributed. Several swirl plates are provided, and a filter cartridge is connected to the bottom of the outer cylinder. A gas swirl homogenizer is installed at the lower part of the regenerator of the regenerative incinerator, and a slag discharge valve is installed under the air inlet pipe connected to the gas swirl homogenizer. The exhaust gas enters the gas swirl plate homogenizer through the air inlet The filter cartridge is filtered, the filtered residue is removed and discharged through the slag discharge valve, and the filtered exhaust gas is evenly diffused and distributed after passing through the swirl plate, so that the flue gas flows through the regenerator more evenly, which can improve the performance of the honeycomb ceramic regenerator. Heat exchange efficiency and service life.

Further, an outer thread is arranged on the outer wall of the filter cylinder, and an inner thread is arranged on the inner wall of the outer cylinder, and the two are connected by a thread. It is convenient to install, dismantle and replace the filter cartridge.

Further, one end of the swirl plate is provided with a plug, the outer cylinder is provided with a corresponding socket, one end of the swirl plate is inserted and matched with the outer cylinder and then welded and connected, and the other end of the swirl plate is provided with a snap joint. The inner cylinder body is provided with a matching clamping groove, and the other end of the swirl plate is clamped with the inner cylinder body and then welded and connected. One end of the swirl plate is positioned through the socket of the plug and the outer cylinder, and the other end is clamped with the slot on the inner cylinder through the card joint, which can accurately connect the swirl plate with the inner cylinder and the outer cylinder. , to avoid the problem of inaccurate connection points caused by direct welding.

Further, the height of the outer cylinder is between 120-300mm, the height of the inner cylinder is 50-200mm, and the vertical distance between the bottom of the inner cylinder and the bottom of the outer cylinder is not less than 50mm. Leave enough space for the installation of the filter cartridge.

Further, the swirl plates are inclined, and the number is 2-10 pieces. So that the exhaust gas can be diffused evenly.

To sum up, the utility model provides a waste gas heat storage device that can filter the waste gas, reduce the smoke and particulate impurities in the waste gas, and at the same time make the airflow evenly distributed, and can improve the heat exchange efficiency and service life of the honeycomb ceramic heat storage body. Type incinerator gas swirl plate homogenizer.
